Sažetak
Phototransfered thermoluminescence (PTTL) found its use in radiation dosimetry for dose reassessment. After the dose has first been evaluated by a common thermoluminescence (TL) measurement, the same dosimeter is subjected to the PTTL dose reassessment with the intention of obtaining a new estimation by a completely independent measurement procedure. Recently, some experimental data indicated that PTTL could be used as a tool for dose discrimination in a mixed field using single TL detector. In this work TL (main dosimetry peak and high temperature peak) and PTTL characteristics for TLD-100 and TLD-700 detectors were investigated for Pu-Be neutrons. The results show that it is possible to determine separately gamma and neutron dose components with a single detector due to different sensitivities of TL and subsequent PTTL to neutrons in comparison to gamma rays. The main disadvantage, the low sensitivity of both, TL and PTTL, to neutrons restricts the use only for the case of radiation accident.
